Zinc finger and BTB domain containing 7B

cKrox, Zbtb7b, Thpok, hcKrox, zfp67
This gene encodes a zinc finger-containing transcription factor that acts as a key regulator of lineage commitment of immature T-cell precursors. It is necessary and sufficient for commitment of CD4 lineage, while its absence causes CD8 commitment. It also functions as a transcriptional repressor of type I collagen genes. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012] (from NCBI)

The microRNA biogenesis machinery modulates lineage commitment during αβ T cell development.
Bassing et al., Philadelphia, United States. In J Immunol, 2014
Dicer-deficient MHCI-restricted αβ T cells fail to normally silence Cd4 and display impaired induction of the CD8 lineage-specifying transcription factor Runx3, whereas Dicer-deficient MHCII-restricted αβ T cells show impaired Cd8 silencing and impaired induction of the CD4 lineage-specifying transcription factor Thpok.

CD4 CTL: living up to the challenge.
Husain et al., Los Angeles, United States. In Semin Immunol, 2013
This lineage dichotomy is controlled by key transcription factors, including the T helper (Th) lineage master regulator, the Th-inducing BTB/POZ domain-containing Kruppel-like zinc-finger transcription factor, ThPOK, (formally cKrox or Zfp67; encoded by Zbtb7b), which suppresses the cytolytic program in major histocompatibility complex (MHC) class II-restricted CD4(+) thymocytes and the Runt related transcription factor 3 (Runx3), which counteracts ThPOK in MHC class I restricted precursor cells and promotes the lineage commitment of CD8αβ(+) cytolytic T lymphocytes (CTL).

Demoor et al., Caen, France. In Tissue Eng Part C Methods, 2013
The specific increase in COL2A1 gene expression observed in the BMP-2 treatment was shown to involve the specific enhancer region of COL2A1 that binds the trans-activators Sox9/L-Sox5/Sox6 and Sp1, which are associated with a decrease in the trans-inhibitors of COL2A1, c-Krox, and p65 subunit of NF-kappaB.
Epigenetic Thpok silencing limits the time window to choose CD4(+) helper-lineage fate in the thymus.
Taniuchi et al., Yokohama, Japan. In Embo J, 2013
Commitment to the helper lineage depends on persistent TCR signals and expression of the ThPOK transcription factor, whereas a ThPOK cis-regulatory element, ThPOK silencer, represses Thpok gene expression during commitment to the cytotoxic lineage.

Taniuchi et al., Yokohama, Japan. In J Immunol, 2013
Differentiation of MHC class II-selected thymocytes toward the CD4(+) helper lineage depends on function of the transcription factor ThPOK, whose expression is repressed in CD8(+) cytotoxic lineage cells by a transcriptional silencer activity within the distal regulatory element (DRE) in the Thpok gene.

The homology analysis of Fugu Th-POK (ZBTB7B) with other known ZBTB7 members (ZBTB7A, 7C) showed low identity, and the phylogenetic tree analysis showed the Fugu Th-POK clustered with the mammalian Th-POK, away from other ZBTB7 members.
